Voronezh (Воро́неж, vɐˈronjɪʂ) is a city and the administrative centre of Voronezh Oblast in southwestern Russia straddling the Voronezh River, located from where it flows into the Don River. The city sits on the Southeastern Railway, which connects western Russia with the Urals and Siberia, the Caucasus and Ukraine, and the M4 highway (Moscow–Voronezh–Rostov-on-Don–Novorossiysk). In recent years the city has experienced rapid population growth, rising in 2021 to 1,057,681, up from 889,680 recorded in the 2010 Census, making it the 14th-most populous city in the country. Information about the original urban layout of Voronezh is contained in the "Patrol Book" of 1615. At that time, the city fortress was logged and located on the banks of the Voronezh River. In plan, it was an irregular quadrangle with a perimeter of about 130 fathoms (238 m), that is, it was very small: inside it, due to lack of space, there was no housing or siege yards, and even the cathedral church was supposed to be taken out. However, at this small fortress there was a large garrison - 666 households of service people. These courtyards were reliably protected by the second line of fortifications by a standing prison on taras with 25 towers covered with earth; behind the prison was a moat, and beyond the moat there were stakes. Voronezh was a typical military settlement, which is clearly evidenced by the decisive predominance of service people in its population (about 70%), mainly "by device". In the city prison there were only settlements of military men: Streletskaya, Kazachya, Belomestnaya atamanskaya, Zatinnaya and Pushkarskaya; The posad population received the territory between the ostrog and the river, where the Monastyrskaya settlements (at the Assumption Monastery) was formed. Subsequently, the Yamnaya Sloboda was added to them, and on the other side of the fort, on the Chizhovka Mountain, the Chizhovskaya Sloboda of archers and Cossacks appeared. As a result, the Voronezh settlements surrounded the fortress in a ring.
